Objective To investigate the expression of serum interleukin-2(IL-2),tumor necrosis factor-α(TNF-α)in the pa-tients with pulmonary tuberculosis and diabetes,and prelininary explore its clinical significance.Methods Experiment were divided into control group(health check-up outpatient,n=10),pulmonary tuberculosis group(n=20),diabetes group(n=20),tuberculosis combine diabetes group(n=20),tuberculosis combine diabetes group was divided into improved group,diabetes group and deterio-rated group after 2 months with therapy according to disease outcome,ELISA assay was used to measured the level of serum IL-2 and TNF-α.Results Before treatment:serum IL-2 levels of pulmonary tuberculosis group,diabetes group and pulmonary tuberculo-sis combine diabetes group were reduced (P<0.05),and the pulmonary tuberculosis group was lower than the pulmonary tubercu-losis group and diabetes group (P<0.05);serum TNF-αlevels of pulmonary tuberculosis combine diabetes group,pulmonary tu-berculosis group and diabetes group increased (P<0.05),and that of pulmonary tuberculosis combine diabetes group was higher than that of diabetes group (P<0.05).After treatment:the level of serum IL-2 increased and TNF-αsignificantly decreased in pul-monary tuberculosis combine diabetes improved group (P<0.05),the deterioration group had no change(P>0.05).Conclusion IL-2 and TNF-αplay a role in the immune pathogenesis of tuberculosis combine diabetes,which dynamic changes can reflect the progression and outcome of pulmonary tuberculosis combine diabetes.

The purpose of this study was to compare Heat Stress Protein70 (HSP70) in human leucocytes, VO2max and Blood Lactate (BLa) during incremental exercise under a thermoneutral condition without taking a sauna with those during the same workload and under same thermoneutral condition after a sauna and after intermittent hypoxia stimuli. Ten unacclimated men performed an incremental test to exhaustion on a treadmill under a thermoneutral condition without taking a sauna (N25℃, relative humidity 65%) and during the same workload and under same thermoneutral condition after a sauna (D25℃, relative humidity 65%), and after intermittent hypoxia stimuli (LN25℃, relative humidity 65%) . The results were as follows: (1) HSP70 levels before incremental exercise in D25℃ were significantly higher than that in N25℃(13701.87?5367.17vs 7517.57?1980.01,P

Objective To study the expression and signiifcance of phospholipid transfer protein (PLTP) and macrophage migration inhibitory factor (MIF) in mice with bronchopulmonary dysplasia (BPD). Methods Ninety-six 4-day-old mice were randomly divided into oxygen group and air group. Mice in oxygen group were exposed to a FiO2 of 65%, and mice in air group were exposed to air. On day 7, 14, 21 and 28, blood and lung tissue samples from 12 randomly selected mice in each group were obtained. The serum levels of MIF and PLTP were measured by ELISA assay. The morphological changes of lung tissue were ob-served with HE staining. Results The mice in oxygen group showed thickened lung parenchyma and obvious pulmonary ifbrosis. The radioactive alveolar count was signiifcantly lower in oxygen group than that in air group (P<0.01). PLTP level in air group was increased gradually from day 7 to day 21, and began to decrease on day 28. PLTP level in oxygen group was increased from day 7 to day 14, and decreased on day 21 and day 28. MIF level in air group did not change during the experiment. MIF level in oxygen group was signiifcantly increased from day 7 to day 21, and began to decrease on day 28. Conclusions MIF and PLTP may be good biomarkers for the diagnosis of BPD.

Objective To explore the application value of diffusion-weighted imaging(DWI) in distinction of skull base chordoma from chondrosarcoma.Methods The clinical data and imaging findings of basicranial tumor confirmed by pathology,including 14 patients with classic chordoma,9 with poorly differentiated chordoma and 18 with chondrosarcoma were analyzed retrospectively.The lesion location,enhancement patterns,signal intensity on T2 WI relative to gray matter,and apparent diffusion coefficient (ADC) values were reviewed.The enhancement pattern was scored as 0 (little or non-enhancement),1 (heterogeneous enhancement),or 2 (homogeneous enhancement in ≥90％area).The data were analysed by Kruskal-Wallis test.Results There were significant differences in the mean,minimum and maximum ADC values,the intensity on T2 WI and the enhancement pattern among the three tumor types (P ＜0.05).However,the differences in the score of enhancement pattern and lesion location were not found (P＞0.05).Conclusion DWI may be helpful for the diagnosis of skull base chordoma from chondrosarcoma,and the accuracy rate will be improved when combined with T2WI intensity.

Objective To investigate the sedative effects of different doses of dexmedetomidine with mid-azolam in spinal anesthesia. Methods 130 cases of spinal anesthesia were randomly divided into 2 groups,group D1 and group D2,with 65 cases in each group. Patients in 2 groups were given midazolam and dexmedetomidine with different doses. The heart rates ,blood pressure ,SpO2 ,Narcotrend value and Ramsay sedation scores were recorded at mutiple time points. The working time ,maintaining time of sedative effect ,and adverse reactions were compared between 2 groups. Results MAP,HR and NT decreased significantly in 2 groups(P < 0.05,respec-tively). The keeping time was relatively longer in group D1 compared with group D2(P<0.05). The working time was faster in group D2 compared with group D1. The rate of bradycardia in group D2 was relatively higher than that in group D1. Conclusion Good sedative effect can be obtained by drug in 2 groups. Group D1,with midazolam 0.05 mg/kg+dexmedetomidine 0.3μg/kg,may have a certain advantage in anaesthesia in the spinal canal.

Objective To investigate the impact of fatty liver on antiviral effect in the patients with chronic hepatitis B (CHB) .Methods A total of 204 patients with hepatitis Be antigen (HBeAg ) positive CHB in the outpatient department of our hospital from January 2011 to April 2014 were selected as the research subjects and divided into the two groups according to wheth‐er complicating fatty liver :the simple CHB group(control group ,122 cases) and CHB complicating nonalcoholic fatty liver disease (NAFID) group(observation group ,82 cases) .The two groups all received the 24‐week antiviral therapy of adefovir (10 mg/d) . The differences in the normalization rate of ALT/AST (biochemical response) ,HBeAg negative conversion rate (serological re‐sponse) and HBV DNA negative conversion rate(virological response) were compared between the two groups .Then the cases ob‐taining the virological response after treatment in the two groups were compared again .Among the cases obtaining virological re‐sponse,thedifferencesinthenormalizationrateofALT/AST(biochemicalresponse)andHBeAgnegativeconversionrate(serologi‐cal response) were compared between the simple CHB group and CHB complicating NAFID group .Results The normalization rate of ALT/AST after 24‐week treatment in the CHB complicating NAFID group was 58 .5% ,which was significantly lower than 72 .1% in the simple CHB group ,the difference was statistically significant ;the negative conversion rate of HBV DNA and HBeAg after 24‐week treatment in the simple CHB group was 67 .2% and 52 .5% ,which were significantly higher than 51 .2% and 37 .8%respectively ,the differences were statistically significant ;among the cases obtaining the virological response ,the normalization rate of ALT/AST in the simple CHB group was 96 .3% ,which was significantly higher than 66 .7% in the CHB complicating NAFID group ,the difference was statistically significant .But among the cases obtaining the virological response ,the negative conversion rate of HBeAg was 78 .0% in the simple CHB group and 73 .8% in the CHB complicating NAFID group ,the simple CHB group was slightly higher than the CHB complicating NAFID group without statistical difference .Conclusion NAFLD has impact on the antiviral effect of adefovir treatment in CHB patients with positive HBeAg ,whereas complicating NAFLD is an important reason for reaching the virological response and serological response ,but without reaching the biochemical response in the antiviral treatment of CHB complicating NAFID .

Objective: To compare the efficacy of induction chemotherapy (IC) plus intensity-modulated radiotherapy (IMRT) with that of concurrent chemo-radiotherapy (CCRT) plus adjuvant chemotherapy (AC) for patients with loco-regionally advanced naso-pharyngeal carcinoma (NPC). Methods:Data of 240 patients with loco-regionally advanced NPC were reviewed. These patients were admitted to the Sun Yat-sen University Cancer Center between January 2004 and December 2008. Among the 240 patients, 117 under-went the IC+IMRT and 123 were treated with the CCRT+AC. The IC+IMRT group received a regimen including cisplatin and 5-fluoro-uracil (5-FU). The CCRT+AC group received cisplatin concurrently with radiotherapy and subsequently received adjuvant cisplatin and 5-FU. The survival rates of the patients were assessed by Kaplan-Meier analysis, and the survival curves were compared by Log-rank test. Multivariate analysis was conducted using Cox proportional hazard regression model. Results:The 5-year overall survival (OS), disease-free survival, distant metastasis-free survival, local relapse-free survival, and the nodal relapse-free survival were 78.0%versus 78.7%, 68.9%versus 67.5%, 79.0%versus 77.0%, 91.6%versus 91.0%, and 95.3%versus 93.7%in the IC+IMRT and CCRT+AC groups, respectively. The survival between the two groups exhibited no significant differences. Higher rates of Grades 3 to 4 nau-sea-vomiting (8.1%vs. 1.7%, P=0.023) and leukopenia (9.7%vs. 0.9%, P=0.006) were observed in the CCRT+AC group. Multivariate analysis revealed that N stage and age were significant prognostic factors for the OS of the patients with loco-regionally advanced NPC. Conclusion:The treatment outcomes of IC+IMRT and CCRT+AC were similar. Distant metastasis remained as the predominant mode of treatment failure.
